European Journal of Taxonomy 459: 1-18, DOI: 10.5852/ejt.2018.459
03E387CEFFE1CB75F768FC0FFA83F862.taxon	diagnosis	Diagnosis (Updated from Townes 1970) Generally small-bodied species (3 – 6 mm), similar to the smaller species of Lathrolestes. Can be distinguished from the latter by the absence of propodeal carinae, except occasional traces of median longitudinal carinae posteriorly, and by the granulate sculpture on the propodeum and T 1. In contrast with other genera of Perilissini, the epicnemial carina in Nanium extends to the anterior margin of the mesopleuron, the pterostigma is short and the marginal cell is also short and deep. The genus can further be characterized as follows: clypeus with ventral margin thick and bluntly rounded, thinner laterally, without small lateral tooth or projection. Ventral margin of clypeus convex. Epistomal sulcus usually distinctly present. Clypeus in profile not projecting or only very weakly angled outwardly from face. Malar space distinct, from very short (0.2 × basal width of mandible) to moderately long (0.3 – 0.5 × basal width of mandible). Diameter of lateral ocellus much shorter than the distance between ocellus and eye. Maxillary palp moderately long, about equal to head height. Female antenna ranging from as long as to slightly, but distinctly, longer than body. Occipital carina dorsally complete, its lower part joining hypostomal carina distinctly above base of mandible. Dorsal end of epicnemial carina extending to anterior margin of mesopleuron. Notaulus varying from nearly absent to distinctly impressed on anterior declivity, extending posteriorly to level of tegula as a weak groove. Groove present between propodeum and metanotum indistinct in lateral view. Propodeal carinae usually completely absent (occasionally traces of median longitudinal carinae). Apex of mid tibia somewhat evenly rounded, with at most a small, weak tooth (similar to several species of genus Perilissus Förster, 1855). Apex of hind tibia with poorly developed comb, with setae widely spaced, not dense. Posterior hind tibial spur at least 7 × longer than maximum width at base. Claws varying from completely pectinate to pectinate only in basal half. Fore wing nearly always with vestigial areolet. Pterostigma short, broad, with Rs + 2 r arising near middle of pterostigma. Hind wing with first abscissa of M + Cu 1 strongly bowed; distal abscissa of Cu l not always discernible but when visible, joining cu-a closer to l A than to M; distal abscissae of 1 A and Cu l spectral, vestigial or absent. T 1 varying from moderately long and slender to shorter, distinctly broadening posteriorly and flattened dorsally. Dorsal carinae absent. Basal depression at dorsal tendon attachment absent. Dorsal-lateral carina absent or nearly so between spiracle and apex of T 1. Glymmae on each side meeting on the midline posterior to dorsal tendon attachment, large, deep, and separated at midline by translucent partition. T 2 with thyridium absent. Ovipositor straight, short, with very broad, deep, subapical depression. Ovipositor sheath from narrowly rectangular to weakly expanding distally. Male parameres broad, rectangular, never strongly narrowed posteriorly. Aedeagus rounded and weakly clubbed distally.	en	Reshchikov, Alexey, Sääksjärvi, Ilari E., Pollet, Marc (2018): Review of the New World genus Nanium Townes, 1967 (Hymenoptera: Ichneumonidae: Ctenopelmatinae), with two new species from the Neotropical region.
